After Dying in a Dungeon, I Changed Class into an Evil Being!

Rossi is an otherwise ordinary university student whose only remarkable qualities are his good looks. His only two talents are sucking up and putting on airs.

A character like him would usually be dead from the start in an infinite-flow world, a disposable extra whose sole purpose is to make the protagonist look good.

Rossi knows for a fact that his cheerful, talkative childhood friend is the protagonist of this book, because he transmigrated into a book.

"Usually, people who transmigrate into a book get a golden finger... Maybe I'm the protagonist of some fanfic too?"

With that hope in mind, Rossi begins his first infinite-flow instance. He manages to stay alive until the end, just as he'd hoped, only to die for good at the very moment he's about to leave the instance.

He's really, truly dead.

His player status is erased, replaced by an identity as an evil entity. He becomes an NPC assigned to work for the instance.

And his faction mentor is the boss who dealt him the final blow in the previous instance.

But Rossi keeps a low profile and survives to the end with his talents for sucking up and putting on airs. He even gets promoted, ultimately becoming the boss of the protagonist's climactic instance.

Childhood friend: ...?

Pairing: A certain faction mentor

Theme: Never give up hope
